PACKING-PAD.

SPECIFICATION forming part of Letters Patent No. 788,561, dated May 2, 1905.

Application filed June 13, 1904:. Serial No. 212,363.

To on whom, it may concern:

Be it known that I, EDGAR J. STEWART, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Packing-Pads, of which the following is a specification and which are illustrated in the accompanyingdrawings, forming a part thereof.

The invention relates particularly to that class of pads which are used in packing goods as, for eXample,furnitureto prevent chafing.

The object of the invention is to secure economy in manufacture, together with increased efiiciency; and the invention consists in a filling composition for pads of this character, as hereinafter described and as illustrated in the accompanying drawings, in which- Figure 1 is a detail perspective of the improved pad. Fig. 2 is a detail section on the line 2 2 of Fig. 1, and Fig. 3 is a detail of the filling.

The pad consists in an envelop or wrapper 10 of any suitable material, preferably of paper, and this envelop may, as shown, be com posed of a single sheet having its edges brought together and secured, as by glue, and a filling of strands of fibrous material 11, such as hay or straw, and which may be approxi mately straight, and a bonding and filling agent of fibrous material 12, such as excelsior, curled hair, moss, or sea-weed which is crinkly or curled. These two kinds of filling material are intermixed in any suitable manner, so that the straighter strands become entangled or intermeshed with the crinkly or curled fibers. The proportions of the various kinds of material may be varied according to the judgment of the manufacturer. The straighter strands may be either tubular, such as straw or certain varieties of hay, or may be flat, as certain other varieties of hay or rushes, and this material has the advantage of cheapness. The crinkly material serves the purpose of retaining the pad in orm.

It has been found in practice that pads made of substantiallystraight strandssuch as hay, straw, &c.are unsatisfactory, partly because the strands are apt to be brittle and become broken into small lengths, but mainly because the strands unless secured by stitching are apt to work to the lower end of the pad, leaving some portions of the casing practically empty.

The crinkly material, whether it'be excelsior, curled hair, moss, seaweed, or any other material having this characteristic, serves as a bond to hold the straighter strands in place, and it also has a cushioning action, which prevents them from being so readily broken. In a pad made as above described no stitching becomes necessary for the purpose of retaining the filling material in place. Each of the two varieties of material has a tendency to increase the elasticity of the other.

The ends of the pad may be open, as indicated in the drawings, and are preferably so. When so made, the material, if substantially straight, such as hay, and not-entangled with a crinkly material, is prone to slide out of the ends of the envelop unless secured by stitching. Pads filled with excelsior only may be discharged of their contents in like manner, although by no means so readily, for the reason that the filling will move as a single mass, while in the case of such material as hay, the strands not being bound together, there is a separation, and a considerable part of the material may drop out, leaving some parts of it still within the casing.

A further advantage in the use of eXcelsior over hay is found in the fact that the filling may be anchored within the case by the use of a sprinkling of glue over it, the wrapper or envelop being applied while the glue is still wet. When so treated, some of the strands of excelsior will adhere to the envelop, and as the mixed mass is entangled a few points of attachment of this kind will entirely prevent the escape of the material from the casing.

I claim as my invention envelop, and a filling consisting of intermixed 1.
